“The cancer is back,” her caption begins. “We are shocked, heartbroken, sad, angry, confused, and just darn tired. Yet, despite how we feel, we KNOW that God is a promise maker and keeper.

“We are deeply saddened to hear the news about Jim Kelly and his impending battle with cancer. Jim is a tough and courageous man and we know he will fight this battle with strength and determination.

The 58-year-old Kelly, inducted into the Pro Football Hall of Fame in 2002, was first diagnosed with cancer in 2013.
